Application filed May 13,

To all 20720712, t /z/zcizz/ concern Be it known that l, ARCHIBALD MONTGOM- iinr Low, of London, England, a subject or' the King or' England, have invented certain new and usetul improvements in and Relating to ipring` Wheels, ot which the following is a specification.

This invention relates to spring wheels. It has been previously proposed to support the rim or periphery either as whole or in part by means oi a series otV leali or laminated springs peripherally around it and located between inner and outer wheel members, said springs being fastened either to the inner or outer portions ot the Wheel or to both.

The present invention has for its object the provision ot' a wheel which, whilst being more particularly of the solid rim type, is so sprung that the outer rim member can move relatively to the inner rim member and said rims can also rotate relatively to each other should such movement benecessary, and with the object of obtaining a wheel in which the springs do not have to receive support in any directionto stand lateral or excessive vertical shocks, according to the present invention' the leaf or lami nated springs which may be set in the inner or outer member of the wheel Aand vpress upon the outer or inner member, as the case may be, are supported or positioned by triction only with regard to both of said wheel members. Y y

To retain said springs in proper position, they are, however, seated in recesses inthe adjacent surface of one or the wheel members. The said springs can naturally be compressed in the direction of shock, but do not allow of side play, the width ot the springs and ot their bearing surfaces on the wheel members preventing or reducing such side-play to a minimum. Such springs it tully compressed require no buffers to prevent damage as with many known constructions and in addition to this latter feature, no lubrication is needed, the springs are easy to conceal, and the dust plates which may be used to cover in the'spaces etween the inner and outer rim portions of the wheel can also be used to hold the tyre. or a detachable or divisible rim or the like in position.

It is well known that such construction does not in any way compare with pneumatic or similar resilient springing, but it i920.- seriai No. 380,979.

has advantage in` preventing certain classes 1 ot vehicles from receiving unnecessary v,

shocks.

An embodiment of the invention given as ignates the innervmember ot the wheel with' its rim Zi, and cthe outer separate rim mem- Y ber. Disposed between said two members is the series of leaf 4or laminated springs d equally spaced around the periphery, said springs being set or seated in recessesy e formed inthe outer surface of the inner member` and bearing freely with their outer ends on the inner surface of the outer rim member. is made between the springs and the wheel members, the former retaining their position by friction whereby a certain amount of relative rotative movement between the wheel members may beL permitted it required. The provision ot the laminated or leaf springs and the width of their bearing surfaces on the wheell members tends to prevent or reduce to a negligible minimum any tendency to side play or lateral movement between the wheel members. As shown in Fig. 2 the ,space between the outer and inner wheel members may be enclosed by plates f for exclusion of dust or the like, said plates being shown as secured by bolts g to the outer rim c and working `freely in recesses it in the sides of the inner rim Z) to provide ior relative verticalvmoveto secure by Letters Patentof the United States is l.
